Hello all!
First post, bit of a lurker.
I recently bought a second hand hybrid for next to nothing and am finding this has its rewards and problems.
This is the issue... the rear gears shift from small to large cog wonderfully, but down the other way is guesswork. It misses cogs out or shifts one gear out of sync then shifts two with the last shift. After a bit of research here I checked the shifter (all ok), the cogs, the chain, none of which seem worn.
However once I came across the bent hanger possibility I thought I'd check the derailleur visually against the one on my perfectly fine no-issues mountain bike. The hybrid swings noticably outward towards the bottom of the derailleur rather than slightly inward as my mountain bike does. Though looking at these photos, I'm wondering if it's the derailleur itself that's bent?
Is there an easy way for me to check this without splashing out unnecessarily on hanger alignment tools?
The derailleur hanger is a shimano megarange job, whereas the mountain bike is a shimano alivio.
I've attached the photos.
